CHARLES P. NICHOLAS AND JOSIILE M. MYERS, OF DAVENPORT, IOVTA.

CHIROPRACTIC APEABATUS.

To all whom it may concern Be it known that we, CHARLES 'P. Nrorro- LAS and Josrarr M. MYERS, citizens of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Chiropractic Apparatus, of which the following is a specification.

Our present invention pertains to chiropractic tables or apparatus for use by chiropractors; and it has for its general object to provide an apparatus constructed with a view to being compactly folded and carried in a case simulating a suit-case, and also constructed with aview to being expeditiously and easily set up in rigid condition and ready for use.

lVith the foregoing in mind the invention in all of its details will be fully understood from the following description and claims, when the same are read in connection ith the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a side elevation showing the head member of our novel apparatus as set up ready for use. Fig. 2 is a plan, showing the suit-case section member of the apparatus as it appears in inverted position, and when ready to be upset and used in connec tion with the head member. Fig. 3 is an inverted plan of the head member as it appears when folded. a is a view showing the head member of the apparatus as it appears when properly arranged in folded condition relative to the folded suit-case section member precedent to applying the closure mem ber of the suit-case, so as to make the exterior appearance of the whole simulate an ordinary suit-case. Fig. 5 is transverse section taken through the apparatus as folded in the suit-case section member and the closure member of the suit-case. Figs. 6, 7 and 8, are enlarged detail views illustrative of the stay-locking device common to the head member and the suit-case section member, as hereinafter described.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

As will be understood by comparison of Figs. 1, 3 and 1 of the drawings, the head member of our novel apparatus comprises a conventional board 1, tapered in width toward one end, a plate 2 fixed to the underside of said board and designed to hold the head member against longitudinal movement Specification of Letters Patent.

than the strip 3, also connected to the underside of the board 1, U-shaped straps 6 connected to the'strip 3, a tubular metallic journal portion 7 held by the straps 6 in the groove 4- of strip 3, divergent tubular metallic legs 8 fixed to and depending from the journal portion 7, and provided at their lower ends with pads 9, straps 10 connected to the strip 5, a tubular metallic ournal portion 11 arranged in said straps, divergent tubular metallic legs 12 fixed to and depending from said journal portion 11 and having pads 13 at their lower ends, a U-shaped stay 14, connected at its ends 15 in a pivotal manner to the legs 8, a similar stay 16 connected in the same manner at 1 to the legs 12, and stay-locking means 18. The said stay-locking means is carried at the under-side of the board 1, and includes a spring strap 19, movable vertically in a groove 20, formed in the underside of the board 1, as best shown in Fig. 8, and equipped with a stud 21. In addition to the said strap 19, the stay-locking device comprises a body plate having lugs 23 and also having a stop 24-, Figs. 6 and 8 and an aperture 25, loosely receiving the stud 21, Figs. 6 and 8, and a locking member 26 pivoted to the body plate 22 and adapted in the position shown in Fig. 6 to bring up againstthe stop 24 and rest over or rather under the pin 21, so as to retain the same flush with or above the underside of the plate 22, and also adapted when in a position at right angles to that shown in Fig. 6, to hold the bights of the stays la and 16 in the inner grooved sides of the lugs 23. it will also be manifest that when the locking member 26 is in the position shown in Fig. 1-2'. 6., in a position at right angles to that shown in Fig. 6, the said locking member 26 will bring up against the stop 24 and stops 27 on the lugs 23, and will be retained against the said stops 24, and 27 by the stud or pin 21, which at that time will have sprung to a position at the opposite side of the locking member 26, with reference to the stop 24. V1 ith the stays 14 looked as described, it will be manifest that there is no liability of the said stays being casually released, and hence the stays will rigidly and safely hold the legs 8 and 12 in the workingposition shown in Fig. 1.

hen it is desired to fold the head memher, the strap 19 is pressed into the board 1 by pressure exerted on its thinnb-piece 28, and as to withdraw "he stud 21. from the underside of the body plate after which the centrally pivoted lockingmember 26 is adjusted or moved to the position shown in Fig. 6 and against the stop l l ith this done, the stays 14- can be readily displaced from the lugs after which the legs 12 are swungfto a position close and parallel to the underside of the board 1, the bight portion ofthe stay 16 being carried through a recess 29in the strip 3. With the legs 12 and stays I6 folded and accommodated as stated, the legs 8 are fol'dedagainst the legs 12, and the stay 14,01 'ather the bight portion of said stay, is extended through a recess 30 provided in the strip As thus folded, the head member is adapted to be placed in proper relation to the suit-case section member, 'andthe suit-case closure section, so that the same can be carried with the same convenience as an ordinary suit-case. See in this connection Figs. 4 and 5.

As will 'be observed by reference to Figs. 1, and 5, the suit-case-section member of our apparatus comprises a body similar to thelargersection of a. suitcase. The said body has a main wall 31 and side walls 52, one of which bears a handle and when said body is supported by the logs under the same, and is arranged in proper relation to the "head member of 1, the whole constitutes an etlicient and conveni nt chiropractic apparatus. I

In addition. to the body referred to, the suit-case section member comprises blocks M connected to the-inner side of the body wall. 31, a strip 35 shallower than the blocks 3 t'also connected to said wall. 31, journal bearing straps 36 and 8'? connected to the blocks 34 and strip'SS, respect-ively,'a tubular metallic journal. portion disposed in the straps'36,tubular metallic legs 39 fixed to thejournal portion 38, a bail-shaped stay 40 pivoted to the legs 89, a tubular metallic journal portion 4-1 disposed inthe straps 37, tubular metallic legs fixed to the journal portiontlg the said legs 39 and 42 being provided with pads Fig. at, a bail-shaped stay Mpiyoted to the legs 42, and a locking device 18 similar in construction to the locking device of the head member and adapted to cooperate with the stays 4. .0 and 4st in the same manner and for the same purpose that the said locking device of the head member, Fig. 1, cooperates with the stays 14: and 16, ie.

With the .parts arranged as shown in Fig. 2, it is simply necessary to upset the suitcase section member and stand the body thereof on its legs in order to adapt said member for chiropractic use in conjunction with the head member-of Fig 1. i i hen it is desired to fold the said slut-case section membenthe stays 40 and 4A: are unlocked, and said stays together with the legs 42 and 39 are swung inwardly and parallel to the body wall. 31; the legs l2 being next to said wall. In addition to the head member of Fig. 1, and the suit-case-section member of Fig. 2, our novel apparatus comprises a suitcase-closure member 50,'Fig. 5.

In folding the apparatus,the head me: ber, folded as shown in Fig. 3, is arranged with its legs against the'legs of the folded suit-case-seCtion member as shown in Fig. l; the plate 2 of the head member bearing against one of the tubular metallic journal portions of the s'uit case-section member, so as to prevent endwise play ofthe head member relative to the suit-casesectionmember.

hen the head member andthe suit-casesection member are relatively arranged as shown in Fig. 4c, and the 'si'iit-case-closure member 50 is applied and connected to the suitcase-section member, as presently described, it will be manifest that thehead member will be crowded against the interior parts of the suit-case -section member,whereupon reason of the resiliency or springiness of the tubular metallic legs and said legs being put under tension, shaking of theparts in the case will be effectually prevented and movement of the head member relative to the suit-case-section member will be effectually -prevented, which is an important advantage. v

The suitcase-closure member 50 is preferably, tho'ugh not necessarily, connected in detachable manner to the body of'the suitcase-section member. In the present and preferred embodiment, the member 5() is provided with projecting tongues 51 on'its lower wall, removablyarranged in sockets 52 in the lower wall of the body of the suit-casesection, and the upper wall of the member 50 is detachably connected with the upper wall of the body of the suit-case-section member by the conventional fastener 'menr bers 53 common in the trunk and suit-case art, or by any other suitable means.

hfla-nifestly when the parts are relatively vrranged as shown in Fig. 5, and the suitcase members are connected together, the apparatus can be handled and carried with the same convenience as an ordinary suitcase. Also when it is desired to setup the apparatus, it is simply necessary 'to unfa'sten the member 50, remove and unfold the head member, and unfold the suitcase-section member, when the said head member and the suitcase-section member can be used in the same manner and for the same purposes as the corresponding members of an ordinary chiropractic apparatus. It will also be manifest from the foregoing that certain features of my invention may be used to advantage in a table of any description.

lVe have entered into a detailed description of the construction and relative arrangement of the parts comprised in the present and preferred embodiment of our invention, in order to impart a full, clear and exact understanding of the said embodiment. \Ve do not desire, however, to be understood as confining ourselves to the said specific construction and relative arrangement of parts as, in the future practice of the invention, such chan es or modifications may be made as do not involve departure from the scope of our invention as claimed. For instance the locking device described may be used on a table of any description.

Having described our invention, what We claim and desire to secure by Letters-Patent, is:

1. The combination with a table having a top and legs hinged thereto; of a base plate fixed to said top and having an aperture and also having depending lugs constructed and arranged to receive brace means and also having a stop, the said brace means engaging said legs and fitting said lugs, a turnbutton pivotally mounted upon said plate and constructed and arrangedto bring up against said stop and to hold said brace means against said lugs, a spring secured at one end to the top and movable between said top and said base plate, and a pin on said spring, extending through the aperture in the base plate to hold the turn-button against said stop.

2. The combination of a member, strips connected to the under side of said member near the ends thereof; one of said strips being deeper than the other, and the strips being constructed and arranged to serve in conjunction with the under side of the memher to form horizontal recesses, transverse journal portions mounted on the under sides of the strips and arranged below said horizontal recesses, legs fixed to said journal portions, bail-shaped stays pivoted to the legs and constructed and arranged in their folded positions to extend through said horizontal recesses, whereby their free portions are retained against the under side of the member, and means on the member constructed and arranged to cooperate with the stays and detaohably secure the stays and the legs in their operative positions.

3. The combination with a table having a top and legs hinged thereto, of a base plate secured to said top provided with lugs extending vertically therefrom and provided with thickened body portions, said lugsprovided with longitudinally extending notches near their inner portions, brace means engaging said legs and fitting within said notches for holding the legs in an extended position, a turn-button pivotally mounted upon said plate and provided with a rectangular body portion, the edges of said body portion fitting between said lugs at a spaced distance therefrom for holding said brace means in engagement with said lugs, means carried by said lugs for limiting the rotation of said button in one direction, said base plate provided with an aperture, a spring secured at one end to said top at a distance from said plate, a pin carried by the free end of said spring, said pin adapted to fit in said aperture for holding said turn button in engagement with said means on the lugs, the upper portion of said lugs being beveled for facilitating the introducing of said brace means behind said lugs and into engagement with said notches.
